I have a problem connecting my Samsung i5800 Galaxy 3 to a PC. First, I could connect to the PC. I had installed the z4root app in order to root my phone and then after installing it, I could not connect to the PC any more.

The dialog to select how to connect to the PC does not appear, though the beep sounds when I connect the phone to the USB cabel. How do I fix this problem?

I had this problem too. It was not related to any driver on the PC as it worked
and stopped working at some point. The problem was on the Android phone which
for some reasons had some configuration problems.

To solve that, dial *#7284# on your phone so that it launches the PhoneUtil
application. Then, switch to the USB -> PDA mode on the phone. Connect the USB cable
(toggle USB -> Modem and then USB -> PDA modes if it does not work the first time)

I have solved the problem in a direct way. I have restored the phone to the factory state, and it worked. And I am convinced it is because of z4root! I have tried the second time and the result was the same. Be careful when you root the Galaxy 3 Samsung i5800 with z4root.
